Doctrine2 - 使用ORM QueryBuilder连接没有关联的实体

Question

是否可以使用ORM QueryBuilder生成用于连接未关联实体的查询,如下所示:

$query = $em->createQuery('SELECT u FROM User u JOIN Blacklist b WITH u.email = b.email');

Answer 1

我不明白为什么不...不管怎么说,QueryBuilder只能转换为DQL.

http://doctrine-orm.readthedocs.org/en/latest/reference/query-builder.html

$qb = $em->createQueryBuilder()
    ->select('u')
    ->from('User', 'u')
    ->join('Blacklist', 'b', 'WITH', 'u.email = b.email')
;
